In this chapter we review the process of parametric down-conversion (PDC) and discuss the different methods to use PDC as a heralded single-photon source.PDC is a non-linear optical process, where an incoming pump photon decays, under energy and momentum conservation, into a photon-pair. The creation of photons in pairs allows for the implementation of

Interference of two photons in parametric down conversion
Physical Review A, 1986A theoretical treatment is given of the process in which the two photons produced simultaneously in the parametric frequency splitting of light are allowed to interfere. It is shown that, while there is no interference in the usual sense involving quantities that are of the second order in the field, fourth-order interference effects are present. These

Hyperentanglement in Parametric Down-Conversion
2003A theory of spontaneous parametric down-conversion, which gives rise to a quantum state that is simultaneously entangled in three-dimensional wavevector and polarization, allows us to understand the unusual characteristics of fourth-order quantum interference in many experiments, including ultrafast parametric down-conversion, the specific example ...

Generalized Bell inequalities with parametric down-conversion
Quantum Information and Computation, 2003We analize the suitability of states generated by stimulated parametric down-conversion for the testing of high dimensional Bell-type inequalities. Two families of bipartite inequalities are considered. For both it is found that the states are good candidates for the tests and some experimental results for one spin-1 inequality are given. The influence

Spatial Quantum Signatures in Parametric Down-Conversion
Physical Review Letters, 1997We calculate the normal and time ordered spatial intensity correlation function of the signal field in a degenerate parametric oscillator below threshold, with spherical mirrors. In the far field, it exhibits a two peak structure, and the correlation is maximal between points opposite each other with respect to the axis of the system.

Parametric down conversion, the spontaneous decay of single photons into highly correlated pairs, is the prime example of quantum optics with x-rays. The effect is very weak, with a cross section of the order of 10-9 of the Thomson scattering cross section. A number of experiments to demonstrate the effect and their results are described here.

Parametric down conversion of X-rays
Optics Communications, 1970Abstract Parametric down conversion of common X-ray sources in a wide range of readily available crystals is calculated to yield high signal-to-noise ratios. A detailed analysis and optimization of experimental parameters is presented.

Hyperentanglement and femtosecond parametric down-conversion
Technical Digest. Summaries of papers presented at the Quantum Electronics and Laser Science Conference. Postconference Technical Digest (IEEE Cat. No.01CH37172), 2002Summary form only given. Entanglement has proven to be an important resource in generating completely new optical states that can be used in quantum information processing, secure communication, and precise optical measurement. The transition from this theoretical notion to experimental reality is often a challenging step, however.

Seeded and Unseeded High-Order Parametric Down-Conversion [PDF]
Physical Review A, 2019 Spontaneous parametric down conversion (SPDC) has been one of the foremost tools in quantum optics for over five decades. Over that time it has been used to demonstrate some of the curious features that arise from quantum mechanics. Despite the success of SPDC, its higher-order analogues have never been observed, even though it has been suggested that ...
